Snooper passes data transparently between two serial (RS232C)
devices, capturing and logging the data and occasional comments you
want to insert into the logs.

It is useful for debugging or analyzing the communications protocol
between two devices that would normally be connected directly to each
other, e.g. a digital camera and a personal computer. By sitting
"in the middle" (after you connect the two devices to serial ports
on your Linux machine) snooper is able to capture data traveling in
either direction while also passing it unmodified to the other device.

It is also possible to operate with a single serial device, using
your console and keyboard as the second device.

The Debian snooper package installs /usr/bin/snooper as a normal
executable program, with no special privileges.
Debian systems normally have the serial devices, /dev/ttyS0,
/dev/ttyS1, etc., secured so that users must be in the group 'dialout'
to read/write those devices.
You should therefore add the user(s) you want to be able to run
snooper to the 'dialout' group. For example, the following
